The size of movement depends upon the change in temperature and the coefficient of thermal expansion o f concrete. The coefficient of thermal expansion of concrete is influenced largely by the coefficient of thermal expansion of the aggregates since the aggregate occupies 70-80% of the volume of the concrete.

Water within the hardened cement paste is forced to more as a result of the applied load. This movement of moisture is the primary cause of creep deformation. Some movement also occurs due to the propagation of microcracks. The movement due to creep can be greater than the elastic strain on loading.

What is Prestressed Concrete? Concrete can withstand a great amount of compressive stress but it has a very low tensile strength. Because of low tensile strength, concrete gets cracks when subjected to maximum load. Why prestressed concrete is used? When water comes in contact with these cracks the steel gets corroded.
